Having Iodine 131 detected in four different places nearly at once,it’s very likely that Fukushima nuc plant has got into recriticality state again.

For now,no public announcement was made as always.They will announce it when it’s too late.

Now it is not sure that in which reactor the recriticality is starting,but from a source,it might be in the spent fuel pool in the third reactor or the forth reactor ,however it’s still an unconfirmed information.

It has been 6 months,but nothing has been improved. Still even a temperature indicator is not properly set at each reactor.It’s almost 100% sure that fuel rods have melted out and started sinking into the ground in some of the reactors.

It’s rational that recriticality will keep happening continuously for decades ,until all of fuel rods are taken out and kept safe.
